2002 Chevy Impala Advice needed desperately!

I noticed that on the previous pages u mentioned thet ur engine light was blinking while u were driving what u should do is drive the car with scanner on snap on will be good and drive with the live window on the scanner on misfire data to see which cylinder is misfiring if u can accomplish that that will take u one step closer to ur problem

My car is now parked at the local Chevy "Stealership" after noticing that my radiator had exploded. They still believe it to be my MAF sensor since I didnt replace it with a OEM GM part.

$1,400 to fix everything and then a diagnostic will be completed. My luck! LOL

Lol, u should ask them b4 u replace maf that why did the rad exploded, in my opinion u hav a compression leak in the cooling system causing tremendeous pressure that sort of explains why would ur engine light will flash,
maf will not cause ur rad to blow up, I hav bought afterrmarket mafs many times
